The best way to debug video drivers is with a serial console. You could 
make grub_serial_putchar() non-static, then call it directly from the 
code you're trying to debug.

Of course it would also be cool if you could output to two consoles at 
once, but I'm not sure if that's currently possible or how to do that.
